Answer:
100 ft squared
Step-by-step explanation: you would usually round up to the nearest whole number with these and 9.7 would round to 10 and 10 times 10 would be 100
<span><span><span>Side c = </span>18</span><span>
<span>Angle B = </span>79°
</span><span><span>Side a = </span><span>12
AB = side b
</span></span></span><span><span>Use the Law of Cosines to find the length of side b.</span><span> <span>
b^2 = </span><span>a^2 + c^2 − 2ac cos(B)</span></span><span> <span>
b^2 = </span><span>(122 + 182) − ( 2 x 12 x 18) cos(79°)</span></span><span>
<span>b^2 = </span>(144 + 324) − 432 x 0.191</span><span> <span>
b^2 = </span>468 - 432 x 0.191</span><span> <span>
b^2 = </span>468 - 82.429</span><span> <span>
b^2 = </span>385.571</span><span>
b = √385.571</span><span>
b = 19.636
Rounded to the nearest tenth is 19.6 cm.
Hope this helps!</span></span>
Answer:
x=1 y=1??
Step-by-step explanation:
1+1=2 i think
have a good day
Answer:
This is one possibility fitting the criteria.
Step-by-step explanation:
I was thinking about using the sine curve because we have that it starts at and not . The factor of 5 came from the amplitude.
So we know so far our function looks like this .
However the inside will be effected since the period is 2.
has a period of .
has a period of .
We want to have a period of 2 so we want to solve .
So multiply both sides by b:
Divide both sides by 2:
.
So the function we have from the given information is:
9x+13=2x+48
-2x -2x
7x+13=48
-13 -13
7x=35
/7 /7
x=5
y=9(5)+13
y=45+13
y=58
